摘要： 为满足集输压力要求、防止井口水合物冻堵，基于井下节流工艺原理，对高压集输井下节流工艺、中低压集输井下节流工艺的选井条件、气嘴直径、下入深度等关键技术参数进行优化设计，并对井筒温度与压力剖面进行模拟。结果表明，井下节流工艺能满足高压集输与中低压集输的压力要求，有效解决了井筒水合物冻堵问题。

Abstract: In order to meet the requirements of gathering and transportation pressure，and prevent wellhead hydrate freeze bloking，design optimization has been made for the downhole throttling process of high-pressure and medium/low-pressure gathering and transportation regarding well selection conditions，gas nozzle diameter，setting depth，and other key technical parameters based on the technological principle of downhole throttling，and wellbore temperature and pressure profiles have been simulated. The results show that the downhole throttling process can meet the pressure requirements of high-pressure and medium/low-pressure gathering and transportation，and effectively solve the problem of wellhead hydrate freeze bloking.

Key words: downhole throttling, hydrate freeze bloking, wellhead temperature and pressure, surface gathering and transportation, Xinjiang Oilfield
